Rule #1: Tweeters consider plagiarism to be blatant stealing – so always remember to acknowledge the original quote-creator, otherwise you will be opening yourself up to serious reputation-damage.

Rule #2: By using the quote, you are directly aligning yourself with that opinion, unless otherwise stated. You need to be accountable for that person’s opinion and be able to substantiate why you are in agreement with it. (People tend to think it was your quote regardless of who said it first!)
